9312167 Freed In this project in the Experimental Physical Chemistry Program of the Chemistry Division, Freed will pursue electron spin resonance (ESR) studies of the dynamics of free radicals in fluids, on surfaces, and in related systems. New relaxation and structural techniques will be used, and the necessary theoretical frameworks for understanding these experiments will be developed and extended. Two-dimensional Fourier transform (2D-FT) ESR, 2D-FT electron-electron double resonance (2D-ELDOR), spin-echo correlation spectroscopy (SECSY)-ESR , dynamic imaging of diffusion (DID)-ESR , and far-infrared (FIR) ESR are among the techniques to be used. %%% In this project Freed will develop several new techniques for electron spin resonance (ESR) which closely parallel new techniques in nuclear magnetic resonance (NMR). These new methods will allow ESR to examine molecular structure and motions more readily in fluids and on surfaces. Such studies will undoubtedly impact many areas of chemistry, biology, and materials science. ***

9312167在化学部实验物理化学计划的这个项目中获得自由，FREED将继续进行流体、表面和相关系统中自由基动力学的电子自旋共振研究。将使用新的松弛和结构技术，并将开发和扩展理解这些实验所需的理论框架。可使用的技术包括二维傅里叶变换(2D-FT)ESR、2D-FT电子-电子双共振(2D-ELDOR)、自旋回波相关光谱(SECSY)-ESR、扩散动态成像(DID)-ESR和远红外(FIR)ESR。在这个项目中，Freed将开发几种电子自旋共振(ESR)的新技术，这些技术与核磁共振(NMR)中的新技术密切相关。这些新方法将使ESR能够更容易地检测流体中和表面上的分子结构和运动。这样的研究无疑将影响化学、生物和材料科学的许多领域。***
